T 0 all whom it may concern Be it known that I, GEORGE D. SLAY- MAKER, a citizen of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Demountable IVheels, of which the following is a specification.

This invention relates to demountable wheels, and has for its object a demountablc wheel seat or ring which can be attached to the front wheel spoke flange or the rear wheel brake drum of almost any car that is now provided with a wooden wheel. The demountable wheel seat or ring is so designed that it makes suitable provision to seat a demountable wheel either on the front or rear axle interchangeably notwithstanding the fact that the bolt holes through the ordinary spoke flange are either not suitable for such an attachment or vary so in their spacing as to make an interchangeable wheel out of the question.

Another feature-of my invention is a new and improved disk wheel adapted to be seated upon this demountable wheel seat or ring and which is reversible, it being permissible to place it with either the tire VillX'G on the inside of the wheel or on the outside. The disk wheel is further provided with a reinforcing disk which eliminates expensive construction in the way of makin a disk of heavy thickness at the center of the wheel and of less thickness near the periphery of the wheel. These features will be better understood and easier to describe after the detailed description has been given.

Fig. 4 is a section of the same taken on the line 4-4 of Fig. 3.

Fig.- 5 is a fragmentary section of the same showing how the threaded studs are attached.

Fig. 6 is a fragmentary section showing a modified form of demountable wheel seat or ring. 7

a designates the channeled metal rim provlded with a valve opening 6. My disk wheel has a main disk 0 that is a stamping. This disk is formed into an intermediate portion (7 which is adapted to occupy substantially the center plane of the -wheel, that is, it is approximately in the plane of the center line of the rim. The section next adjoining the section (ion the inside thereof forms a sort of annular channel 6 with flaring side walls. The section next adjoining the section d on the outside thereof is the section f which angles away from the middle section rl toward the outer edge of the rim. The disk then curves slightly back forming the outer section 9 which runs to the rim, Where it turns rightangularly and runs parallel, forming the rim seat 71. The channeled felly or rim can be secured to this I'lIIl seat by welding, riveting or other means. This angling away from the middle plane of the wheel forms a chamber all around the disk to receive the air valve.

The angling section also forms a seat for the reinforcing disk j, the'major portion of which is formed into a shallow conical portion approximately on the same angle as the angling section 7' ofthe main disk. The inner portion of this disk 7' is formed into a section complementary to the annular channel section 0 of the main disk. In order to accomplish this the conical portion of the reinforcing disk is turned in sharply at 71:, from which it continues in a plane parallel with the middle plane of the wheel to form a section Z that parallelsthe bottom of the annular channel 0 of the main section. The extreme inner portion of the disk is turned in at an angle to form an abutment m that meets the similarly turnedin abutment n of the main disk. Between the bottom of the-annular channel 2 of the main disk and the flat section I of the reinforcing disk is placed and confined the Wooden spacer ring 0. The reinforcing disk I abutments meet-.1 Between the main disk and relnforcing disk in the space not occupied by the wooden spacing ring I use mineral wool or other fillingmaterial to deaden the sound and dampen the-hum set up by vibrating parts.

The disk wheel constructed on the lines and in the configuration just described is artistic and possesses great strength. It further has the advantage of being reversible, that is to say, the wheelcan be placed with the tire valve on the inside, as shown v in Fig. 1, or it may be easily reversed to be placed with the tire valve on the outside, as shown in Fig. 2, without in any way altering the gage of the wheels from wheel to wheel. This is due to the use of the reinforcing disk and the spacer, which makes the distance from the surface that abuts against the wheel seat to the center line of the wheel the same on either side of the wheel.

Referring to Figs. 3 to 9 inclusive, the various forms of demountable wheel seats and rings will be understood. I -provide a ring r'which is flared in at the periphery to form the shallow hell 8 for a purpose to be described Near the center of this ring the same flares in to form an angular seat t and a hub ring u. The angular seat t is adapted to form a fairly wide bearingfor the angular abutment m or 'n of the disk wheel. The flaring portion 8 at the periphery of the ring in conjunction with the turned-in section I: of the reinforcing disk affords an ad ditional seatfor the disk wheel at a position somewhat more removed from the center of the wheel, where it is much more effective in stabilizing the wheel. Inasmuch as the wheel will almost always be used by motorists in the position shown in Fig. 1, this forms a very secure hold for the wheel upon the axle.

In a'great many cars the wooden spoke flanges either have too many bolt holes for the attachment of a demountable wheel or else the number of bolt holes in the flanges of the front and rear wheel hubs varies and there is varying spacing so that ademountable wheel designed to be placed on a front wheel hub would be unsuitable for placing on the rear wheel hub. My demountable wheel seat or ring makes possible the accommodation of a demountable wheel of uniform construction on either the front or rear hub on almost any car. The ring can be provided with a special arrangement of inwardly-projecting studs suitably placed for conditions found on any car or on either the front or'rear hub. These threaded studs are adapted to pass through the inner spoke flange that is usually an integralpart of the hub. Nuts :I/ may then be run on the ends after the studs have been passed through the hub flange and brake drum. and this securely clamps the demountable wheel seat or ring to the brake drum and spoke flange. The outwardly-projecting studs 2 can be uniformly arranged for taking a uniform demountable wheel and they can be the same for the front and rear wheel hubs although ferred construction, if this the inwardly-projecting studs w may have to be specially arranged for this purpose. These studs are welded into countersunk portions as shown in Figs. 4 and 5. However, in Figs. 7 and 9, I have shown an arrangement of two demountable wheel seat rings and headed studs. The purpose of this is to prevent the studs being pulled out of the weld by turning the nuts down too tightly, for it will be seen that the opening through one disk is slightly less than the diameter of the head of the stud, and consequently any excess strain due to turning the nut down too tightly is taken by the head of the nut and the abutting disk. In Figs. 8 and 9 in place of showing a threaded stud welded to the disk and a nut, I have shown threaded sockets and cap screws. This is merely an equivalent construction- In Fig. 6, I have shown the inner studs :1: and the outer studs 2 in the form of a single stud passing clear through the ring. This is possible in some cars and of course a pre: is possible. Where the front and rear wheels have the bolt holes through the spoke flange spaced at the same points and suitably spaced to form driving studs for a demountable wheel, such a form of ring may be used.

From the showing in Fig. 1, it will be seen that the outwardly-projecting studs .2 not only act as driving studs but they also serve to receive the nuts 1 by whichthe wheel is demountably secured to the demountable wheel seat or ring. If this form is not desired, the outwardly-projecting stud may be a simple stud, as shown in Fig. 2, and the demountable wheel ring or seat has an extended hub ring 3 that is externally threaded to receive the nut 4, which is provided with a conical seat adapted to I engage against the turned in abutment m or n.
